This Thruster Fin fits the Islander Lip Stick and Big Stick surf kayaks. It fits most wave ski makes and models (center fin) as well as the Shane Universal. Also fits some sit-in-side surf kayaks such as the Riot Boogie. Many of the surf kayaks will take sides fins too. This Thruster Fin is for use with a 3/8 inch surfboard style fin box. Comes with mounting screw and plate. When installed in the fin box, it will be 5 inches in depth. It has an overall height of 5 7/8 inches when it is not in the fin slot. Fits all Islander BigStik surf kayaks. Identical to Islander part number 9810029, made by Islander's old supplier. See the Five-O Fin for Islander LipStik kayaks built before 2002. May or may not have a logo on it.
